POLYFLEX M

Description

Two part latex modified cementitious waterproofing coating

 

Polyflex M is a two part modified acrylic cementitious coating, mixed at site for easy application. It cures to form a tough flexible coating with excellent waterproofing properties.

Properties

  • Excellent performance and flexible in nature 
  • Good adhesion to most surfaces 
  • Non toxic, therefore suitable for potable water. 
  • Resistant to carbon dioxide and chloride ion diffusion. (Forms a film that provides an anti carbonation coating over concrete. A 1mm coating of Polyflex M provides anti carbonation cover which is equivalent to over 75 cm of concrete). 
  • Can resist up to 3 Bars of pressure. 
  • Unlike conventional coatings which require 7– 28 days cure of concrete, Polyflex M can be applied to 24 hours old concrete, there by giving immediate protection to the concrete. 
  • Allows the substrate to breathe.

Step by step

SURFACE PREPARATION

The surface must be sound and free of oil, grease, dust and other unwanted residual material which will affect the bonding. The surface to be treated should be pre-saturated with water prior to application but remove any standing water prior to application.

MIXING

Polyflex M is supplied in two parts, and pre measured. On site mixing is needed. Pour the liquid into a suitably sized container and slowly add the powder to the liquid and mix using a slow speed drill (300-400rpm) fitted with a suitable paddle until a lump free creamy consistency is obtained. Do not mix more material than that can be used within 45 minutes. Never add water to loosen the material at any stage.

APPLICATION

Apply the first coat using sufficient material at a rate of 1.75kg/m2 to completely cover the holes, cracks etc. A soft bristled brush or roller can be employed for this. Once the first coat is dry, apply a second coat in order to achieve the required thickness at an average rate of 1.75kg/m2 per coat. After the application of the first coat and whilst the coating is still wet, embed a glass fibre mesh (CL 252 or similar materials) at all corners and other joints for added reinforcement. The second coat shall be applied after the first coat dries off completely (6-8 hours @25°C, 50% rh). For general protection against carbonation and alkali attacks, the coating can be applied in minimum 1mm thickness.
